Example 1.1: Black Roller, Opening motives, mm. 1-4
Most of the motivic development is confined to the opening of the piece. In the first
twelve measures, motive x is presented six times, inverted once, permeated in three
different ways, and presented as an embellished variant at [b∣. Example 1.2 outlines the
various methods used to develop this motive.
Example 1.2: Motive x development in Black Roller
A musical expectation of frequent use and variation of motive x is set up in the
opening, and although it occurs more frequently than any other motive, it is abandoned
for large sections of the piece. Figure 2 identifies the most important motives in the work
and illustrates how they are used throughout the piece.
